Vielo R+1 Strato Shimano GRX RX600

Tipping the scales at 1100g the R+1 Strato frame is all about on-road performance. With space for 32mm tyres, comfort and grip aren't left off the back though! This 1x-specific design might be a bit disconcerting to some, but here is what Vielo have to say:

"1x is no fad. It's the logical next step for road bikes. Lose the second chainring and you gain a beautiful symmetry. Nothing is offset, with a perfectly balanced downtube, bottom bracket and chainstay contributing to 30% greater lateral stiffness. Tube shapes are designed to maximise aero efficiency, and with less cabling (especially in the Alto version) streamlining is optimal and clutter minimal."
